Pint Glass Microphone

Inspiration for the "Pint-Crophone" came about at Karaoke when I saw several random patrons bellowing into their pints (during a Journey song, of course). Some of these people show up each week, but never actually get up and sing. Others sing into their pints whilst waiting for their turn on the mic. It struck me that this was a serious waste of awesome karaoke rockin. The Pint-Crophone would strive to remedy this by retrofitting the bottom of a standard pint glass to contain a transducer mic and wireless transmitter. Mics would route into a standard mixer that the Karaoke DJ could adjust/mute accordingly. Would-be crooners could now sing into their beer and provide backing vocals on select songs ("Don't Stop Believin", "Bohemian Rhapsody", the woo-woos on "Sympathy for the Devil") where a bawdy choral element is prefered. Depending on the level of beer in the glass, a lovely warble distortion may occur and add even more character to the backing vocals (great for middle-period Beatles and 80's New Wave). Further refinements could include using a rim-mounted mic (for less distortion) or a hydrophone (for more distortion). Most die-hard karaoke fans, myself included, are also fantastic drunks, so bars could offer the Pint-Crophone option as a sort of premium for returning customers or beer-of-the-month club members. The pint-crophone system would have to be self-contained and removable, for cleanup purposes. You could stack them up for battery charging similar to those annoying vibrating table pagers that chain establishments fancy. Only these would be way cooler.
